Even high efficiency central air systems are not designed to withstand multiple seasons of use without additional coolant. They create the cold air through direct expansion coils or chilled water coils as the warmer air is blown across them.

In the typical central air conditioning unit the cooling cycle is an ongoing process of cool refrigerant absorbing heat from indoor air and expanding into a warm gas traveling to an outdoor unit where it expels that heat and returns to a cool liquid then returning back indoors to absorb more heat and continue the cycle.
Does modern home air conditioning use coolant. A central air conditioning system conditions the air and delivers it through vents throughout your home. UPGRADE YOUR SYSTEM TO USE A MODERN COOLANT The EPA has approved several new coolants the most popular of which is R-410A commonly marked under the brand name Puron. Air conditioning also AC air con is the process of removing heat and controlling the humidity of the air within a building or vehicle to achieve a more comfortable interior environment.
Contained within the coils of an air conditioner these liquid agents cool and dehumidify indoor air. The advent of air conditioning has shaped our homes and family life as well. You can think of a home air conditioner as a type of refrigerator.
This may be achieved using powered devices air conditioners by passive cooling or by ventilative cooling. For years the most common refrigerant used in air-conditioning systems was R-22. Lennox has led the way in the manufacture of cooling systems that use chlorine-free R-410A refrigerant.
At Ocean State Air Conditioning Heating we offer Comfort and Performance geothermal heat pump systems. Some go a step further and set the temperature higher when no ones home. If you look closely at our top photo you can see that the fan has a green Ozone friendly label on it which means there are no CFC coolants inside.
This chemical is an HFC hydrofluorocarbon but has been shown not to harm the ozone and since 2015 has become the standard for residential air conditioning. A central air system uses the most electricity but does the cooling job most effectively as evidenced by the fact that 86 of people who live in Florida use central AC to cool their home. It is a constant cycle of hot air in and cold air out that provides comfort in your home and car.
This coolant is a hydro-chlorofluorocarbon HCFC a type of coolant that is no longer used because it causes ozone depletion. Most modern air conditioners avoid CFCs now banned in many countries under a global agreement called the Montreal Protocol and use alternative coolant chemicals instead typically halogenated chlorofluorocarbons or HCFCs. What Benefits Do Geothermal Systems Offer Homeowners.
Houses are designed not for ventilation but for central cooling systems. In response to growing environmental concerns production of systems using R-22 refrigerant is being phased out. However you cant just pour R-410A into a cooling system that uses R-22.
Home air conditioners work by removing the heated air and humidity in the room and replacing it with colder air. The AC compresses the R-22 gas making it very hot. They call it conditioning because heating only adds heat and displaces moisture whereas cooling REMOVES both heat and moisture.
In this form the cooled R-22 absorbs the heat from the outside air then pushes the cold air out. Use of this coolant is prohibited in all HVAC units after 2015. Ive never paid any attention to this detail while inspecting houses because it didnt make much difference but thats.
Most air conditioners use one of two types of refrigerant. Your AC may be on its last legs no longer able to keep up and needing replaced or your home could need a coolant recharge. But dont lower the temperature below 78 to cool the house down faster.
Modern air conditioning is just a heat pump. Some of the systems parts will have to be replaced. Geothermal HVAC systems offer several advantages for home heating and cooling for Florida homeowners.
Most newer AC units use a refrigerant called R410A or Puron. These heat pumps are among some of the most innovative units available for home use. R-410A is a type of HFC refrigerant that is widely used in newer AC units replacing older HCFC coolants.
Refrigerants are what make air conditioning possible. One common issue as the summer heat is coming to an end and our mild autumn begins is low coolant. If youre lucky youll never have to change the coolant in your air conditioning system.
When this gas moves through the coils it cools down to a liquid form. R-22 is no longer used for new air conditioning systems a change that became effective in 2010. The air conditioner cools at the same rate no matter where its set.
The equipment is designed with a closed loop if nothing goes wrong the coolant should last for the life of your AC unit. Many people are good about leaving the air conditioner at the recommended 78 degrees. A common brand name for R-22 is Freon.
Its the most effective but also the most expensive. However there are occasions when the air conditioning system could leak or malfunction which can require replacement of the coolant. Isnt heating the air a form of conditioning the air as well.
R-410A is a mixture of two other HFC refrigerants R-125 and R-32 and offers greater cooling properties than older HCFC refrigerants when they are subjected to higher pressures. Impact on Homeowners with Older AC Units. By One Hour Heating Air Conditioning.
